Summarize your learnings in a series of blogs:

• create a new folder 'javascript'
• organize series in subfolders
• one blog per week
• focus on learning javascript
• should have a theoretical and practical part
  • theoretical: use references as much as possible
  • practical: use examples, challenges, code snippets
    • evaluate gist for code snippets: https://gist.github.com
    • evaluate stackblitz and codepen.io for code examples
• first blog deadline: 17.04.2020 (next Friday)

Please remember: put all your exercises and notes on your personal github repo. Use git and vi :)!

Here is one little exercise: map a one-dimensional array into a 2-dimensional matrix (=table).

Given input is a one dimensional array like:

• const data = [1,2,3,4,5,6,7,8,9]
• const data = [1,2,3,4,5,6,7,8,9, 10, 11]
• const data = ["a", "b", c"]

Transform input into a nested/two-dimensional array. Like
[1,2,3,4,5,6,7,8,9] => [ [1,2,3], [4,5,6],[7,8,9]]

Provide two types of solutions:

1. "Imperative style" using for loop
2. "functional style" using map, filter, reduce (functions on array)
